Rear Axle 3.73 Ratio

Rear Axle 3.73 Ratio: The Ultimate Guide for Car Enthusiasts

As a car enthusiast, the phrase “rear axle 3.73 ratio” might sound like music to your ears. It’s the fundamental factor in determining how fast a car can go and how much torque it can deliver.

In this comprehensive guide, we’ll take you through everything you need to know about rear axle 3.73 ratios, including its significance, how it works, its advantages and disadvantages and where you can find them.

Understanding Rear Axle 3.73 Ratio

The rear axle 3.73 ratio is a mathematical expression that represents the number of revolutions the axle turns versus the revolutions of the driveshaft. In simpler terms, it’s the ratio between the number of revolutions made by the wheels and the engine crankshaft per minute.

The 3.73 ratio means that the wheels make 3.73 rotations while the engine crankshaft turns once. Alternatively, if the engine crankshaft rotates 3.73 times, the wheels will only turn once.

As seen in the above description, the ratio carries significant weight in determining how fast a car can go. A higher ratio means the wheel can turn faster, leading to a higher top speed of the car.

For example, the 3.73 ratio offers more pulling power than the 2.73 ratio, but you must trade off some fuel economy as you reach a higher speed. Therefore, the rear axle 3.73 ratio is a key factor for car enthusiasts when deciding on their perfect car acceleration and top speed.

Advantages of Rear Axle 3.73 Ratio

One of the main advantages of rear axle 3.73 ratios is that they can target the specific driving style of car enthusiasts. These ratios are tailored to allow fast acceleration with a lower torque, as well as higher speeds like highway speeds.

Hence, if you enjoy driving at high speed, a 3.73 Ratio may be a good choice. The ratio enables your car to deliver more power thus allowing you to overtake cars more easily, especially on highways.

Additionally, rear axle 3.73 ratios are a popular choice for towing due to their ability to deliver a high amount of torque. The extra torque helps provide more pulling power and allows you to add more weight than vehicles with a lower gear ratio.

Disadvantages of Rear Axle 3.73 Ratio

Despite the advantages of rear axle 3.73 ratios, there are some drawbacks you should be aware of when considering its application on your vehicle. One of the main disadvantages is the lower fuel economy, which can cause an increase in fuel consumption.

With a 3.73 ratio, the engine spins faster, which requires you to use more fuel to maintain the same speed. In brief, if you use this ratio on a car with poor gas mileage, be prepared to part ways with more fuel money.

Also, the 3.73 ratio may not be suitable for your car if you daily commute to a place that requires stopping and starting frequently such as a city. This ratio may give you a jolt each time you start your car, leading to higher engine and drivetrain wear and tear.

Where Can You Find Rear Axle 3.73 Ratio?

Suppose you’re interested in purchasing a car with a rear axle 3.73 ratio, where can you find one? Typically, you can find these ratios in performance-oriented vehicles, such as sports cars, muscle cars, and off-road trucks.

One of the most famous examples is the Ford Mustang, which has been using the 3.73 rear axle ratio since its introduction in 1979. Additionally, many Chevy Camaro models use the 3.73 ratio in their rear axle configuration.

If you’re interested in off-road vehicles or trucks, the RAM 1500 Rebel is a great choice. It features a 3.73 ratio for the rear axle, allowing you to navigate terrain easily.
